ABSTRACT:
The disclosed shoulder ballast cleaning machine with integrated hopper car is particularly designed to provide for the temporary conveyance and storage of clean ballast. The shoulder ballast cleaning machine digs up the stone ballast of the railroad bed, separates dirt and debris from the ballast, and replaces the cleaned ballast on the railroad bed. The hopper car provides the storage capacity to have ballast on board for deployment on the track bed when the quantity of ballast then being cleaned is inadequate to satisfy the need and to store excess cleaned ballast when the quantity of cleaned ballast exceeds the amount needed to be replaced on the track bed. The hopper car is interposed between the power car and the auxiliary car. A unique conveyor system conveys the fouled ballast from the power car where the ballast is dug up, past the hopper car, to the auxiliary car where the ballast and waste are separated. A further unique conveyor system conveys the cleaned ballast from the separator on the auxiliary car to the hopper car for redeployment on the track bed.
